2.11.4.2 Global Set Fuse

The Global Set Fuse determines if all R-cells and I/O registers (InReg, OutReg, and EnReg) are either cleared or preset by driving the GCLR and GPSET inputs of all R-cells and I/O Registers (see Figure 2-32). Default setting is to clear all registers (GCLR = 0 and GPSET =1) at device power-up. When the GBSETFUS option is checked during FUSE file generation, all registers are preset (GCLR = 1 and GPSET= 0). A local CLR or PRESET will take precedence over this setting. Both pins are pulled High during normal device operation. For use details, see the Libero IDE online help.
